CEDARBURG — A man who owns an Ozaukee County restaurant is being investigated on allegations that he drugged women's drinks, sexually assaulted them and took nude photos of them.

Federal, state and local law enforcement authorities raided the man's Wauwatosa home and Cedarburg restaurant. A search warrant filed Monday says they seized cameras, computers and drugs, including a numbing agent used in minor surgery.

The Associated Press is not naming the 34-year-old because he has not been charged.

Authorities previously investigated him in 2008 after several women said he offered them drinks, and that they had foggy memories afterward. One says she received a text photo of herself without pants, with a text that read, "round 2?"

Cedarburg police say new allegations in April led to the renewed investigation.
